Installation
A311-03-880 Issue A
3.6 Connect the cooling-water pipelines
Note: Refer to Section 2.4 for the cooling-water requirements. Note that there are minimum flow rate
requirements specified.
Connect your cooling-water pipelines as follows:
1. Refer to Figure 1 detail D. Connect the cooling-water supply pipeline to the cooling-water inlet (20).
2. Connect the cooling-water return pipeline to the cooling-water outlet (19).
Refer to Section 2.4 for the minimum cooling-water flow rate required. Do not allow the cooling-water supply
pressure to go above the maximum pressure stated in Section 2.4 .
3.7 Fit the drive/transmission (bareshaft HV8000 pumps only)
CAUTION
Your drive and transmission system design must ensure that the maximum pump rotational speeds specified in
Section 2.3 cannot be exceeded, otherwise the pump will be damaged, or may not operate correctly.
If you are using one of the motor mounting kits, then continue at Section 3.7.1
You must use a suitable coupling or a belt drive and transmission system to connect your drive to bareshaft HV8000
pumps.
Your drive and transmission system design must ensure that the maximum radial loadings on the pump drive shaft
are less than those specified in
Table 12 . On a belt drive system, ensure that the pulley fitted to the drive shaft has
a diameter larger than the minimum diameter specified in Table 13 .
Connect the components of the drive and transmission system to the pump drive shaft (see Figure 2 and 4 ) as
described in the manufacturer’s instructions supplied with the components.
After you have connected the drive/transmission, continue at Section 3.10 , to check for correct direction of rotation
of the HV8000 pump.
WARNING
Ensure that the drive/transmission is suitable for use with your pump/system.
WARNING
You must fit suitable guards to protect people from rotating/moving parts.
